Monique Andrée Serf (9 June 1930 – 24 November 1997), known as Barbara, was a French singer. She took her stage name from her grandmother, Varvara Brodsky, a native of Odesa, Ukraine. Barbara became a famous cabaretière in the late 1950s in Paris, known as La Chanteuse de minuit ('the midnight singer'), before she started composing her own tracks, which brought her to fame. Her most famous songs include "Dis, quand reviendras-tu ?" (1962), "Ma plus belle histoire d'amour" (1966) and "L'Aigle noir" (1970), the latter of which is said to have sold over 1 million copies in just twelve hours.
